我们利用纳米操纵实验和分子动力学模拟研究了多壁纳米管在轴向压缩下的轴向屈曲。实验上，对于相同外径，不同内径的纳米管的杨氏模量与基于连续介质分析的欧拉屈曲模型一致。三壁和双壁纳米管的屈曲行为的MD模拟也与连续分析一致。这一良好的一致性表明，欧拉屈曲模型适用于多壁纳米管的轴向屈曲行为的分析。
We have investigated the axial buckling of multiwall nanotubes under the axial compression using nanomanipulation experiments and molecular dynamics (MD) simulations. Experimentally, Young's moduli of nanotubes with different inner hollow diameters for the same outer diameters are consistent with the Eulers buckling model based on the continuum analysis. The MD simulations for the buckling behavior of triple- and double-walled nanotubes are also consistent with the continuum analysis. This good agreement indicates that Euler's buckling model is applicable to the analysis of the axial buckling behavior of the multiwall nanotubes.
